(CNN) -- Around 75,000 people from Kyrgyzstan remain displaced a month after the eruption of ethnic violence in the country's south, the U.N. refugee agency said Friday.
People fled their homes in the region because of sectarian violence between ethnic Uzbeks and Kyrgyz, some heading into neighboring Uzbekistan and others finding shelter elsewhere in Kyrgyzstan.
The office of the U.N. High Commissioner for Refugees said 400,000 people were uprooted at one point.
Some of the displaced were afraid to return to their homes. Others had to find other shelter because their homes were destroyed.
The agency said that Osh and Jalal-Abad, two cities where major violence flared, are now calm. However, the mood in the country is uneasy.
"Thousands continue to be affected by uncertain security, problems arising from the wide loss of personal documents, and a shortage of shelter," the agency said.
"There are nonetheless scores of police checkpoints, and the two cities remain under night-time curfew. This in turn is presenting difficulties for people without personal papers, and there are frequent allegations of police harassment," it said.
